Experience

1. Software Engineer

   Upstart

   Feb 2023 — Present · Columbus, OH, US

   I play a key role in ensuring the reliability and scalability of Upstart’s loan processing platform by designing, developing, and maintaining its backend services and infrastructure. I develop and maintain microservices using Java, Spring Boot, and Spring Batch to drive critical business logic and complex data workflows. I leverage AWS cloud services for scalable, reliable deployments, with Docker and Kubernetes for container orchestration.I manage asynchronous workflows and messaging with Kafka and SQS, monitor application performance with CloudWatch, and optimize APIs using GraphQL and Spring WebFlux. I collaborate daily with DevOps and QA engineers to ensure secure, efficient deployments, mentor junior developers, lead large-scale data processing with Spring Batch, and increase test coverage through TDD practices with JUnit 5 and Mockito.
